Abstract
The invention generally relates to a method and device for contacting contact areas (22) with probe tips (18) in a tester. The contact areas (22), which are arranged on a substrate (6), and the probe tips (18) are positioned relative to each other and then brought in contact with each other by an advancing motion. In order to detect a secure contact for each of the probe tips (18), the contacting between the probe tips (18) and the contact areas (22) is observed from at least two observation directions (34), which include an observation angle α in a range of 0 to 180°.
